I just wanted to report here that I was able to use the MyPhoneExplorer application designed for Sony Ericsson phones available at
http://www.fjsoft.at/en/downloads.phpIt detected the LG modem driver with the USB cable but didn't work, however using the toshiba bluetooth drivers with the phone connected as a serial com port it worked and I can browse and transfer the contacts and phone files & microsd and other functions via bluetooth, you probably could get it to work with other bluetooth drivers as long as serial port emulation is an available function
however it looks the built in file browser cannot see the system files like you can do via the bluetooth obextool in linux
